We learned a lot from this year's Nuart festival, and the many questions and conversations we had with artists and organziers alike, was that by the time the installations opened on Saturday to kick of the Nuart exhibition, it was clear that Europe has a group of street and conceptual artists making provocative and challenging works just at a time that the battle between street art and curated muralism has reached a critical mass.

This year's Nuart Plus program, a series of lectures, talks, and academic debates (okay, the debate is in a pub, and the academics get thrown out the window a few drinks in) have kicked off as the murals, street interventions, and installations are in progress at Nuart in Stavanger, Norway. The spirit of this year's academic portion, and the spirit of Nuart in general in 2014, is the battle of unsanctioned street art versus the ongoing, curated mural festivals popping up around the world.

A few weeks ago, Tilt's half graffiti, half-pristine hotel room, aka the Panic Room, circulated blogs around the world as a visual stunner of a project. The room resides inside the Au Vieux Panier hotel in Marseille, France. Today, Tilt just sent us a video of the process and story behind the Panic Room, a great chance to revisit the project. Watch after the jump . . .

We always like to see what TILT is working on, and we just saw that he completed the Panic Room, a hotel room of half graffiti, half clean slate, pristine white. TILT did the Panic Room inside the Au Vieux Panier hotel in Marseille, France, where 5 artists transformed 5 different rooms in their own signature style.

A nice, simple video from Montana Colors that captures TILT doing multiple black and white pieces overlapping each other. This is Montana's first video in the Big Addict series, and captures the hypnotic, and of course, obsessive nature of a graffiti artist. The video was directed by Benjamin Roudet. Good work.

We love the way Tilt is described: a French graffiti artist, renowned for painting on buildings, canvases and naked women. To the point. In conjunction with Tilt's print by London's Pictures On Walls of the Union Jack is made up of lyrics from the Sex Pistols "God Save the Queen," POW invited Tilt to paint a large mural of said print in London and Big Addict shot the video.

Nothing says Columbus Day releases like a TILT "Sex & Violence" print release at Pictures on Walls in London. We like how POW puts it: the day "marks the achievements of an unrelenting self-promoting social climber who brought exploitation, slavery and deadly diseases to the Americas." So let's have a sex and violence print.
